Does Simscale support Craig-Bampton FE model reduction?


#1

I need to get the mass and stiffness matrices of a reduced-order finite-element model, preferably with the reduction done using the Craig-Bampton method. Does Simscale do model reduction and, if so, does it support the Craig-Bampton method? Thanks!

Hi @tsoares and sorry that I missed this post, thought I already answered it :slight_smile:

I am not sure if every FE module has this reduction method implemented but from what I have seen the dynamic solver has it (I guess under specific circumstances) - will ask my colleagues and get back to you as soon as I know more.

Best,

Thanks! It would be awesome if there was a way to get a reduced model. Is there a way to get mass and stiffness matrices from Simscale?
